I’ve just attempted a restore from a Win10 image from a 2017 MacBook Pro to a 2018 MacBook Pro with no success. 2018 restore was attempted by using BootCamp to create the partition, which configures the appropriate trust settings for Secure Boot, and then using Winclone to restore the partition into that space. I also disabled Secure Boot but with the same results (INACCESSIBLE_BOOT_DEVICE). I also saw the same when attempting to boot the 2017’s BootCamp partition via thunderbolt target disk mode on the 2018 system.
I can boot the OS without issue using VMware Fusion.
The Windows 7 driver install method assumes that the OS can boot, but I am struggling to install BootCamp while the OS is not booted natively (it obviously fails under VMware, as it doesn’t have direct access to the hardware), Installing the driver (right clicking the .inf file) doesn’t help - the driver needs to be installed and ready to go or else the system won’t boot at all.
I have yet to figure out how to install a driver for a device that’s not actually visible in Windows.
